Right for you, today
The same protein bar is a good call at 4pm and a poor one at 10pm.
Honest comparison
Kata vs Yuka.
Yuka is one of the most genuinely independent apps in health, and its score is honest work. It is also identical for every person who scans that barcode.
The verdictAn incorruptible score in the aisle. And why it can never be about you.
First, fairly
Yuka at a glance.
What it is for
A barcode scanner that grades packaged food and cosmetics from 0 to 100 and suggests better alternatives.
What it costs
Free to download and scan. Premium is annual only and pay what you want, starting at 10 USD, 10 GBP or 10 EUR: offline scanning, search without scanning, dietary alerts. The features are identical at every price, the higher amounts are voluntary support.
Where it is strongest
No ads, no money from brands, revenue published openly, and a scoring method anyone can check.
Who it suits
Anyone who wants an instant, incorruptible second opinion on a packaged product in the aisle.

Why Kata
Three reasons, not thirty.
One system
Food, training, sleep, supplements, labs and mood in a single place.
It decides
Not a dashboard you read: a coach that says what today should look like.
It stays yours
Your logs, chats, photos and the coach's memory live on your device.
Honestly
When Yuka is the better choice.
In the supermarket aisle, Yuka is better and Kata is not trying to replace it. An instant, incorruptible second opinion on a jar you have never bought, from a company that takes nothing from brands, is worth having. Keep it.
In short
What, how and why.
- What
- Kata is a personal health coach, not a scanner.
- How
- It works from your own numbers: what you already ate, your phase, tonight's session.
- Why
- The yoghurt scores 68. Whether it fits your day is a different question.

Questions
Asked and answered.
Is the Yuka score personalised to me?
No. Yuka's published method uses no information about you: the same product returns the same score for everyone. Premium Alerts can flag gluten, lactose or palm oil, but they do not change the score. For a shopping tool that is defensible.
Does Kata have a barcode scanner?
No. You tell Kata what you ate, in words or with a photo. Plenty of people use both: Yuka to decide what goes in the basket, Kata to decide what the day needs.
